I just bout a Palladium S550 coupe. Has Sport package, came with 19" stock rims. Will the 20-inch AMG 10-spoke forged wheels (Black) from a S63 "plug and play?"

Also, if anyone knows where to find a take off set, please advise.

Congrats on the purchase. I believe they will fit fine but they are a $2200 upgrade on the S63 so they will be harder to find than the stock wheels that many will pull off... I'd watch the classifieds here and also Ebay. I've seen a few sets of S65 five split-spoke wheels for sale too, they also should fit.
